To all whom t may concern.'

Be it known that I, Ronnn'r DIXON, a citizen of the United States, residing at Armells, in the county of Fergus and State of Montana, have invented new and useful Improvements in Motor-Flows, of which the following is a specification.

This invention relates t0 motor` plows and it consists in the novel features hereinafter described and claimed. i

An object of the invention is to provide a simple, and improved construction of motor plow with means for manipulating or handling the movable parts thereof in order that the plow may be operated by one person who may supervise the propulsion o1 movement of the plow and the turning of the same in a field.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of partsv which will be hereinafter fully described and particularly claimed.

In the accompanying'drawing has been illustrated a simple and preferred form of the invention, it being however, understood that no limitation is necessarily madeto the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the accompanying drawing:

. Figure 1 is a top plan view of the motor plow;

Fig. 2 is a side elevation of the same;

Fig. 3 is a transverse sectional view of the same;

Fig. 4 is a detailed horizontal sectional view of a compensating gear used upon the plow;

Fig. 5 is a fragmentary detailed sectional view of a modified form of a digger which may be used upon the plow.

The plow comprises a frame or platform 1 which is mounted at its forward end upon dirigible 0r steering wheels 2. Any suitable means may be provided for steering or guiding the wheels 2. Wheels 3 have their hubs 4 journaled in the rear portion of the frame 1 and at the sides thereof. Sprocket wheels 5 are fixed to the hubs 4. Shafts 6 are journaled upon the intermediate portion of the frame 1 and the said shafts are in longitudinal alinement with each other.

Sprocket wheels 7 are mounted upon the shafts 6 and sprocket chains 8 are trained around the sprocket wheels 5 and 7 and are adapted to transmit rotary movementl from the shafts 6 to theV hubs 4 and wheels 3. Beveled gear wheels 9 are fixed to the inner ends of the shafts 6 and constitute part of a compensating gear mechanism indicated in general at 10. This mechanism is of a usual structure and operatively connects the shafts 6 together although'it may permit one shaft to rotate in one direction while the other shaft is rotating in an opposite direction.

An engine 11 is mounted upon the frame 1 and a shaft 12 loosely carries at its rear end a beveled pinion 13 which Ymeshes with the teeth of a drum 14 which is ,part of the compensating gear 10. The gear wheel 13 is provided with a clutch hub 15 and a clutch member 16 is slidably mounted upon the shaft 12 and may be moved into engagement with the hub 15 whereby the wheel 13 is fixed with relation to the shaft.121 hence it will be seen that when the shaft 12 is rotated Arotaryv movement is transmitted by the wheel 13 and compensating gear 10 to the shafts 6. Thus means areprovided for propellingthe machine over the surface of the ground. A yoke 17 is pivotally mounted at its ends upon the Outer portions of the hubs 4 and the said yoke carries at its rear intermediate portion a scraper blade 18. A bail 19 is pivotally connected with the intermediate portions of the side of the yoke 17 and a cable 20 is connected at one end with the bail 19 and is trainedover a pulley 21 which is journaled. upon a derrick structure 22 mounted upon the frame 1. .A winch 23 is journaled for rotation at the intermediate portion of the frame 1 and the cable 2O is arranged to wind thereon. A beveled gearwheel 24 is carried by the said shaft and meshes with a bevel gear wheel 25 which `is provided with sprocket teeth 26.

A sprocket wheel 27 is loosely mounted upon the shaft 12 hereinbefore described and a sprocket chain 28 is trained around the 'sprocket wheel 27 and the teeth 26 of the wheel 25. A clutch member 29 is slidably mounted upon the shaft 12 and may engage the hub of the wheel 28 whereby the wheel 28 is fixed with relation to the shaft 12. Consequently when the clutch member 29 is in engagement with the hub of the wheel 28 and the shaft 12 is rotating rotary movement is transmitted by the `chain 27 and connected Wheels to the shaft of the withinl the drum 32 and spaced therefrom.l

Tangentia'lly disposed diggers 34 are carried by the drum 32 and cylinder 33. As the drum 32 rotates the diggers 34V enter the soil and till or turn the same in a usual manner.

A shaft 35 is iournaled for rotation in Athe hubs 4 of the wheels 3 and is provided at its ends with'sprocket wheels 36. Chains 37 are trained around the wheels 36 and wheels `31 and 4are adapted to transmit rotarymovement from the shaft 35 t0 the shaft 30 which in turn rotates the drum 32 as herein- Y before described.

The sprocket wheel 38 is loosely mounted on the shaft 35 and is provided with a clutch hub 39 adapted to be engaged by Ia yclutch member 40 slidably mounted on the shaft Vwhereby the wheel 38 is fixed with relation to the shaftl 35. A. chain41 is trained around the wheel 38 and the drum 14 ofthe compensating mechanism and is adapted to transmit' rotary movement from the said drum tothe .shaft '35 when the clutch memb'er 40 is in engagement with the hub Consequently it will be seen vthat means are provided for rotating the drum 32 from the engine n. f In the modified form of digger as'fillustrated in Fig'. 5 of the draw-ing the same consists of an active end p'ortion 42 which passes through the drum 32 and which is provided at 'its inner end with a shank v43. An abutment member 44 is fixed in the cylinder 33 and the shank 43 passes longitudi- 'Y nally through the said abutment member. A

coil spring 45 is interposed between the Vadjacent ends of the abutment member 44 and the active portion 42 vand surrounds thepintermediate part of the shank 43. The active portion 42 is slidably mounted in the drum 32. Consequently as the said active portion enters the ground and encounters an' obstruction asfor instance a large stone or rock the spring 43 will contract whereby the active portion 42vmay move or pass vover the' rock and slide in the drum 32. rThus the tilling mechanism Vmay pass over rocky ground without lifting the same by forcing rigid diggers in contact withfobstructions in theground. "1 A From theforegoing Vdescription taken in conjunction withthe accompanying drawdurable structure is provided and that the same may be economically used or manipulated by a single operator to eHect the propulsion of the plow and to accomplish the turning of the same at the ends of rows or at any point within'a eld. f
